Will there be any problems swapping an lt1 into a 83 z 28 with a 305 cfi? I also want to swap in the auto tranny.

 

Nothing big I suspect, I upgraded my CFI car to TPI and again recently to an LS1.

If your car had a TH200C trans (3-speed auto), you'll need to either use an aftermarket trans crossmember, or drill the two rearward holes for the stock crossmember. The TH200C is quite a bit shorter than TH700R4 or 4L60E trannies, and the frame holes for the crossmember are farther forward.

 

nope, my tranny is the 700r4 with overdrive.

 

Good deal, that was the only headache w/ my swap. The rest is pretty cookie-cutter type stuff, the wiring is no more of a hassle on a CFI car than the other models.

 

did you have any problems sticking that ls1 in? I was considering that route, but i dont think i can afford it right now.

 

Nope, it dropped right onto the Spohn engine mounts I installed. Wiring was no more painful than the previous TPI swap. Gauges are a minor hassle w/ the LS1...coolant temp is incorrect, tach is way off, no cable-drive speedo.
